How many electricians does it take to change a light bulb in Melbourne?

The answer is of course, one, because electricians in Melbourne are licensed professionals who know what watts are which. For those of us who aren’t qualified electricians, changing a light bulb might not prove that easy. If you would like to learn a bit more about the electricity powering your home then have a look at some of the electrical jargon listed blow.

• A watt equals voltage times by amps. This equation looks much like this, x amount of volts times by y amount of amps = xy watts.
• A watt is a unit of electrical power that tells us how much electricity we’re consuming. A watt is a tiny measurement for power usage so kilo and mega are used to make things easier. For instance, 1 kilowatt = 1,000 watts while 1 megawatt = 1,000 kilowatts or 1 million watts.
• A wire’s gauge rating describes the maximum current that can travel through a wire. For instance a wire with 14 as the gauge value means that it has a 15 amps capacity. A wire with 6-gauge value has a 55 amps capacity.
• All modern electrical systems are grounded for our protection
• James Watt and Thomas Edison combined their inventions, the steam engine and the generator respectively, to produce the first large-scale electricity generation.
• Resistance in a conductor opposes the flow of an electric current. Resistance is measured in ohms. Ohms law stimulates that the smaller the wire or conductor, the greater the resistance to a current. On the one hand, resistance can result in heating along the circuit, which you need to minimize due to the risk of dangerous hot wires. On the other hand, by building resistance into a circuit you are able to control the strength of the current running through it.
• The amp was so named after Andre Marie Ampere, the French developer of the field of electrodynamics. The unit of electric current thus was first called an ampere in his honor, but was simplified into an amp by the Americans.
• The Ohm was so named after Georg Simon Ohm, a German physicist and mathematician from Cologne. Ohm discovered the relationship among resistance, current and voltage.
• The term capacity refers to the amount of current or amps that a wire can carry before it exceeds its temperate rating. Capacity is determined by wire size, type and insulation.
• The terms volts, amps, and watts are common measurements of electricity 

It is important to consider the types of wire that are in your home. There are a few different types of wiring systems that could be lighting your home. This is why it is important to consult an electrician to ensure that your wires are handled appropriately. Before the 1950s, most homes were wired with what is called knob-and-tube wiring, a complicated system that only an experienced electrician should be allowed to go near. The armor-clad cable system was installed mostly during the 1920s and 30s in more upmarket areas. The problem with this system was that wires were wrapped in metal, which proved dangerous if the metal started to rust and age or heat to extreme temperatures. Current wiring systems use non-metallic sheathed cable, wrapped in thermoplastic. This system is very safe due to the mixture of hot and neutral wires and a grounding wire to increase safety. These modern systems are also very easy to install.
